If you're starting a new article, you can develop it here until it's ready to go live. If you're working on improvements to an existing article, copy only one section at a time of the article to this sandbox to work on, and be sure to use an edit summary linking to the article you copied from. Do not copy over the entire article. You can find additional instructions here. Remember to save your work regularly using the "Publish page" button. (It just means 'save'; it will still be in the sandbox.) You can add bold formatting to your additions to differentiate them from existing content. |

[edit]Main article: Physical hazard
Physical hazards are a subtype of occupational hazards that involve environmental hazards that can cause harm with or without contact. Physical hazards include ergonomic hazards, radiation, heat and cold stress, vibration hazards, and noise hazards.
Heat and cold stress
Heat and cold stress occur when the temperature is significantly different than room temperature (68-74 degrees Fahrenheit). When the body is exposed to heat stress, excess sweating can lead to a range of heat-related illnesses [1]. Excessive cold can also lead to several cold-related illnesses[2].
Vibration hazards
Occupational vibration hazards most often occur when a worker is operating machinery that vibrates as a symptom of its functioning (e.g., chainsaws, power drills, etc.). With the most common type of vibration syndrome being Hand Arm Vibration Syndrome (HAVS), long-term exposure to HAVS can lead to damage occurring in the blood vessels, nerves, muscles, and joints of the hand, wrist, and arm [3].
Noise[edit]
[edit]Each year in the US, twenty-two million workers are exposed to noise levels that could potentially harm their health. Occupational hearing loss is the most common occupational illness in the manufacturing sector. Workers in certain fields, such as musicians, mine workers, and even those involved with stock car racing, are exposed to higher levels of noise and therefore are at a higher risk of developing hearing loss.
While permanent, noise-induced hearing loss is preventable. As such a widespread issue, NIOSH has been committed to preventing future hearing loss for workers by establishing recommended exposure limits (RELs) of 85 dB(A) for an 8-house time-weighed average (TWA). The Buy Quiet program was developed by NIOSH to encourage employers to reduce workplace noise levels by purchasing quieter models of tools and machinery. Additionally, a partnership with the National Hearing Conservation Association (NHCA) has resulted in the creation of the Safe-in-Sound Award to recognize excellence and innovation in the field of hearing loss prevention.
